Time Measure of the code inside the node js (only use for benchmarking)

Time_Measure.js

// Node.js Time measure for benchmarking

// Way One : in microseconds
var hrTime1 = process.hrtime();
// code
var hrTime1 = process.hrtime();
startP = hrTime[0] * 1000000 + hrTime[1] / 1000;
endP = hrTime1[0] * 1000000 + hrTime1[1] / 1000;
// Shows the time difference in micro second
console.log(endP - startP);

// Way Two : in nanoseconds
const start = process.hrtime();
// Code
const end = process.hrtime(start);
// Shows time in nano seconds
console.log("\n%d nanoseconds", end[0]*1e9 + end[1]);


// Way Three : In seconds
const start = process.hrtime();
// ....code to process
const end = process.hrtime(start);
console.log("\n%d seconds", end[0] + end[1] / 1000000000);
